发明名称 Cellkoppling och förfarande för styrning av cellerna via denna
摘要 A cell switch includes a plurality of ports, each being two-way connected to a switch core by means of two transmission channels extending in a respective direction. Tagging devices are provided in the ports for creating, based upon destination information in the head of an incoming cell, a tag belonging to the cell and containing information enabling directing of the cell through the core to the right port. In the core tags are received which have been sent in advance before the corresponding cell and, based upon the information included therein, scheduling information regarding sending times of the respective cells from the ports is created for such scheduling that during these sending times the cells can be sent to the destination ports without conflict arising with other earlier scheduled cells. This scheduling information is sent to the ports of origin of the cells. The cells are retained in the ports until it is time to send them into the core in their respective scheduled sending times.
